The Baiji is a now extinct species of river dolphin that lived exclusively in the Yangtze River in China. The Baiji or Goddess of the Yangtze was known by a number of different names such as Yangtze Dolphin, Chinese River Dolphin, Whitefin Dolphin and the Yangtze River Dolphin. Although the Baiji is currently believed to be extinct there is a possibility that a handful are alive within captivity although this is not known for sure.

Conservation programs were underway to protect the Baiji which was suffering due to the industrial growth of China where the Yangtze River was becoming used more frequently for transportation, fish and hydro-electricity programs. Sadly the conservation efforts proved to be too little too late as an expedition in 2006 encounters not one Baiji.

Humans are without a doubt the main reason for the extinction of the Baiji. Whether the Baiji was being hunted for food, caught in fishing nets or being killed my electric fishing and collisions with boats the finger still points at humans.
